Sixteeen sets of original laboratory data collected by many investigators for various Cutthroat flume sizes are thoroughly reviewed and organized. Best-fit discharge parameters are obtained by performing the free-flow analysis and the submerged-flow analysis. Then, the transition submergence can be calculated. Afterwards, the unified free-flow and submerged-flow discharge parameter s are developed for each flume size in order to generalize the calibrations for Cutthroat flumes. This is a very tedious process requiring a trial-and-error approach. Finally, comparisons are made of the measured laboratory discharges with the predicted discharges for both free flow and submerged flow using both the best-fit and the unified discharge parameters.
The results proved quite good as measured by the standard deviation for each flume size. In most cases, the average standard deviation using the unified discharge parameters was only slightly greater than when using the best-fit discharge parameters. However, there is a significant difference in the accuracy of free-flow measurements compared with submerged-flow measurements. Using the unified discharge parameters, the mean standard deviation for all of the flumes was 2.1 percent for free flow and 6.5 percent for submerged flow.
